Abstract
Starch is modified by reacting it in the presence of an alkaline catalyst and more than 10% of water by weight of dry starch with an ester of (1) an aromatic carboxylic acid or an aliphatic polycarboxylic acid and an ethylenically unsaturated alcohol having 2 or 3 carbon atoms or (2) an aliphatic monocarboxylic acid and an ethylenically unsaturated alcohol having 3 carbon atoms. Specified esters are vinyl benzoate, vinyl phenylacetate, vinyl naphthoate and allylidene diacetate. The reaction may be effected at a pH of 7,5-12,5 and a temperature of 75 DEG -115 DEG F., the mixture being neutralized to pH 6,5 with hydrochloric or sulphuric acids and the product dried with the aid of methanol, ethanol or acetone. Suitable catalysts are sodium carbonate, alkali metal hydroxides, quaternary ammonium hydroxides, ammonium hydroxides or aliphatic amines. The starch may be derived from roots, stems or seeds. Specifications 489,330 and 890,083 are referred to.
